Description

Technical Field

[0001] This invention relates to the field of logistics warehousing technology, and in particular to an explosion-proof stacker crane for logistics warehousing and its control method. Background Technology

[0002] Logistics warehousing is a key hub in the circulation of goods from production to consumption, carrying out centralized storage, safekeeping, sorting, and distribution of goods. It plays an important role in regulating supply and demand and optimizing supply chain costs and efficiency. Stacker cranes, as the core equipment of automated warehouses, can achieve precise storage and retrieval of goods in both vertical and horizontal directions through high-precision track movement and intelligent control systems. They are especially suitable for high-density, large-capacity racking scenarios.

[0003] Existing patent CN221987251U discloses a stacker crane for logistics warehousing, comprising: a lifting plate, with a first insert plate and a second insert plate fixedly connected to both ends of one side of the lifting plate, anti-slip pads provided on the top of both the first and second insert plates, a connecting plate fixedly connected between the first and second insert plates, and a side rod fixedly connected to one side of both the first and second insert plates. When a cylinder pushes the first clamping plate outside the side rod to move inward, a swing rod at the bottom of the first clamping plate drives a rotating rod at the bottom of the connecting plate to swing, causing the second clamping plate to move synchronously with the first clamping plate. This facilitates the clamping and fixing of goods placed inside the first and second insert plates, preventing accidental falls when the device lifts the goods, and thus improving the stability during goods transportation.

[0004] However, in the aforementioned existing technologies, there is a lack of isolation and protection functions for flammable and explosive goods during transfer and placement, which seriously affects the safety of the transportation and placement process. Summary of the Invention

[0005] The purpose of this invention is to provide an explosion-proof stacker crane for logistics warehousing and its control method, which solves the problem in the prior art that there is a lack of isolation and protection functions for flammable and explosive goods during transfer and placement operations, which seriously affects the safety of the transportation and placement process.

[0006] To achieve the above objectives, the present invention provides an explosion-proof stacker crane for logistics warehousing, comprising a plate inserter and a support frame. Both ends of the plate inserter are provided with fixed seats. A semi-explosion-proof cover is rotatably mounted on each fixed seat via a rotating shaft. Each rotating shaft is provided with a worm gear. The fixed seat is also provided with a mounting box. A worm is rotatably mounted inside the mounting box, meshing with the worm gear, and the worm gear extends into the mounting box. The worm between two mounting boxes is driven by a dual-axis motor. A lifting mechanism is provided on the support frame, and the plate inserter is located at the moving end of the lifting mechanism.

[0007] The insert plate frame is equipped with a rear explosion-proof plate, and one side of the half-explosion-proof cover has a side through hole that can accommodate the rear explosion-proof plate.

[0008] The bottom explosion-proof plate is provided below the half-section explosion-proof cover via multiple connecting rods.

[0009] The rear end of the insert plate frame is provided with two positioning sleeves, and the bracket is provided with two positioning rods, with the two positioning sleeves respectively fitted onto the corresponding positioning rods.

[0010] The explosion-proof stacker crane for logistics warehousing also includes a push handle and multiple casters. The push handle is located on the rear end face of the support, and the multiple casters are respectively located below the support.

[0011] The explosion-proof stacker crane for logistics warehousing also includes multiple weight-adding blocks and a placement box. The multiple weight-adding blocks are stacked in the placement box. The placement box is fixedly connected to the support and is located on the rear end face of the support and below the push handle.

[0012] The present invention also provides a control method for an explosion-proof stacker crane used in logistics warehousing, applied to the aforementioned explosion-proof stacker crane used in logistics warehousing, comprising the following steps:

[0013] S1: By using the push handle and the casters, the explosion-proof stacker is moved to the designated location where goods need to be picked up, and the staff places the goods on the insert rack;

[0014] S2: Start the dual-axis motor, which drives the worm gear to rotate clockwise. The worm wheel rotates accordingly, which in turn drives the rotating shaft to rotate, causing the half-explosion-proof cover fixed on it to rotate around the rotating shaft. The two half-explosion-proof covers then merge inward to cover the goods.

[0015] S3: Then, based on the push handle and the casters, move the explosion-proof stacker to the position where it needs to be stacked, and control the dual-axis motor to drive the worm gear to rotate counterclockwise, so that the two half-explosion-proof covers unfold inward and outward respectively;

[0016] S4: Based on the stacking height requirements of the goods, the moving end of the lifting mechanism is controlled to make the insert frame lift the goods. When the goods reach the specified stacking height, the operation of the lifting mechanism is stopped, and the goods are accurately placed at the target position.

[0017] S5: After the goods are stacked, control the lifting mechanism to lower the insert rack to the initial position.

[0018] This invention discloses an explosion-proof stacker crane for logistics warehousing and its control method. By setting fixed seats at both ends of a plate rack, a semi-explosion-proof cover is rotatably mounted on the fixed seats via a rotating shaft. The opening and closing of the semi-explosion-proof cover can be achieved using a worm gear structure and a dual-axis motor drive, providing protection for goods. The rear explosion-proof plate on the plate rack and the side through-holes on the semi-explosion-proof cover that accommodate the rear explosion-proof plate further enhance the protection of the rear end of the goods. A bottom explosion-proof plate, connected by multiple connecting rods below the semi-explosion-proof cover, can provide protection for the bottom of the goods. The system provides protection; the two positioning sleeves at the rear end of the insert plate frame cooperate with the two positioning rods inside the bracket to ensure the stability of the insert plate frame during lifting; the push handle at the rear end of the bracket and the multiple casters below it facilitate the movement of the stacker crane; the multiple weight-adding blocks stacked in the placement box located at the rear end of the bracket and below the push handle can increase the stability of the stacker crane and prevent danger caused by shaking during the transfer and placement of flammable and explosive goods, thus comprehensively solving the problem of lack of isolation and protection functions for goods and improving safety during transportation and placement.

Detailed Implementation

[0031] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0032] First embodiment:

[0033] Please see Figures 1-5This invention provides an explosion-proof stacker crane for logistics warehousing, comprising a plate rack 101 and a support 102. Both ends of the plate rack 101 are provided with fixed seats 103. A semi-explosion-proof cover 105 is rotatably mounted on each fixed seat 103 via a rotating shaft 104. Each rotating shaft 104 is provided with a worm gear 106. The fixed seat 103 is also provided with a mounting box 107. A worm gear 108 is rotatably mounted inside the mounting box 107, meshing with the worm gear 106, and the worm gear 106 extends into the mounting box 107. The worm gear 108 between two mounting boxes 107 is driven by a dual-axis motor 109. A lifting mechanism 110 is provided on the support 102, and the plate rack 101 is located at the moving end of the lifting mechanism 110.

[0034] In this specific embodiment, the insert plate frame 101 and the bracket 102 are used as the basic structure. Fixed seats 103 are provided at both ends of the insert plate frame 101, and a semi-explosion-proof cover 105 is rotatably mounted on the fixed seats 103 using rotating shafts 104, providing initial side protection for the goods. Simultaneously, a worm gear 106 is provided on each rotating shaft 104, and a worm 108, meshing with the worm gear 106, is rotatably mounted within the mounting box 107 on the fixed seat 103, extending into the mounting box 107. The dual-axis motor 109 drives the worm 108 between the two mounting boxes 107, enabling the opening and closing of the semi-explosion-proof cover 105 via motor drive. This design not only facilitates the loading and unloading of goods but also effectively isolates goods from the external environment during transportation and placement, preventing flammable and explosive goods from posing a danger due to external factors, greatly improving the safety of goods transfer and placement in logistics warehousing operations. Furthermore, the lifting mechanism 110 provided on the support 102 and the insertion plate rack 101 located at the moving end of the lifting mechanism 110 allow the insertion plate rack 101 to be flexibly adjusted according to the height requirements of goods storage, thereby improving the applicability and operational efficiency of the stacker crane.

[0035] The insert plate frame 101 is provided with a rear explosion-proof plate 111, and one side of the half-explosion-proof cover 105 has a side through hole 112 that can accommodate the rear explosion-proof plate 111.

[0036] In this embodiment, during cargo transfer and placement, the rear explosion-proof plate 111 effectively isolates and protects the rear end of the cargo, preventing flammable and explosive goods from leaking from the rear or being affected by external fire sources. The design of the side through-hole 112 ensures that it does not interfere with the rear explosion-proof plate 111 when the half-explosion-proof cover 105 is closed, guaranteeing coordinated operation between the various protective components. This comprehensively improves the safety of the cargo during transportation and placement, effectively solving the problem of insufficient isolation and protection for the rear end of the cargo.

[0037] Secondly, a bottom explosion-proof plate 113 is provided below the half-fan explosion-proof cover 105 via multiple connecting rods.

[0038] In this embodiment, the bottom explosion-proof plate 113 provides a protective barrier for the bottom of the goods.

[0039] Meanwhile, the rear end of the insert plate frame 101 is provided with two positioning sleeves 114, and the bracket 102 is provided with two positioning rods 115, and the two positioning sleeves 114 are respectively fitted onto the corresponding positioning rods 115.

[0040] In this embodiment, when the lifting mechanism 110 drives the insert plate frame 101 to move up and down, the cooperation of the positioning sleeve 114 and the positioning rod 115 can ensure that the insert plate frame 101 always maintains a stable movement trajectory, avoiding swaying, deviation and other situations.

[0041] In addition, the explosion-proof stacker crane for logistics warehousing also includes a push handle 116 and a plurality of casters 117. The push handle 116 is disposed on the rear end face of the support 102, and the plurality of casters 117 are respectively disposed below the support 102.

[0042] In this embodiment, the push handle 116 provides a convenient operating point for the operator, who can control the movement direction of the stacker by holding the push handle 116; while the multiple casters 117 enable the stacker to move flexibly in all directions, making it easier and more convenient to drive in a straight line or turn.

[0043] Finally, the explosion-proof stacker crane for logistics warehousing also includes multiple weight-adding blocks 118 and a placement box 119. The multiple weight-adding blocks 118 are stacked in the placement box 119. The placement box 119 is fixedly connected to the support 102 and is located on the rear end face of the support 102, and is also located below the push handle 116.

[0044] In this embodiment, when transferring and placing flammable and explosive goods, the stacker crane may be subjected to various external forces, such as the impact force during loading and unloading of goods, and the shaking caused by uneven ground. If the stacker crane itself is too light, it is prone to tipping over and other dangerous situations under these external forces. The weight-increasing block 118 can effectively increase the center of gravity of the stacker crane, making it more stable and reducing the risk of tipping over.

[0045] When using an explosion-proof stacker crane for logistics warehousing according to this embodiment, the explosion-proof stacker crane is moved to the designated location where goods need to be retrieved by the cooperation of the push handle 116 and the universal wheel 117. The staff places the goods on the insert rack 101; the dual-axis motor 109 is started, and the dual-axis motor 109 drives the worm gear 108 to rotate clockwise, and the worm wheel 106 rotates accordingly, thereby driving the rotating shaft 104 to rotate, so that the half-explosion-proof cover 105 fixed thereon rotates around the rotating shaft 104, and the two half-explosion-proof covers 105 respectively merge inward to cover the goods; then based on the Push the handle 116 and the casters 117 to move the explosion-proof stacker to the desired stacking position. Control the dual-axis motor 109 to drive the worm gear 108 to rotate counterclockwise, and the two half-explosion-proof covers 105 unfold inward and outward respectively. Then, according to the stacking height requirements of the goods, control the moving end of the lifting mechanism 110 to make the insert frame 101 lift the goods. When the goods reach the specified stacking height, stop the operation of the lifting mechanism 110 and accurately place the goods in the target position. After the goods are stacked, control the lifting mechanism 110 to lower the insert frame 101 to the initial position.

[0046] Second embodiment:

[0047] Based on the first embodiment, please refer to Figures 6-9 This invention provides an explosion-proof stacker crane for logistics warehousing. The lifting mechanism 110 includes two threaded sleeves 201, two lifting screws 202, and a support box 203. A power component is provided on the support box 203. The two threaded sleeves 201 are symmetrically arranged on the insert frame 101. The two threaded sleeves 201 are also threaded onto the corresponding lifting screws 202. The two lifting screws 202 are rotatably connected to the support 102 through bearings and are located on the support 102. The two lifting screws 202 are connected to each other through a synchronous belt 204 and a synchronous pulley 205. The support box 203 is located above the support 102 and covers the synchronous belt 204 and the synchronous pulley 205. One of the synchronous pulleys 205 is driven by the power component.

[0048] In this embodiment, the power unit is activated, which drives one of the synchronous pulleys 205 to rotate. Since the two lifting screws 202 are connected to the synchronous pulleys 205 via the synchronous belt 204, when one synchronous pulley 205 rotates, it will drive the other synchronous pulley 205 to rotate synchronously via the synchronous belt 204, thereby causing the two lifting screws 202 to rotate simultaneously. Under the rotation of the lifting screws 202, the threaded sleeve 201 will move linearly along the lifting screws 202, thereby driving the insert plate frame 101 to rise or fall.

[0049] The power component includes a drive gear 206, a driven gear 207, and a protective box 208. The drive gear 206 is rotatably connected to the protective box 208 and is located inside the protective box 208. The drive gear 206 is driven by a power motor 209. The driven gear 207 is rotatably connected to the protective box 208 and is located inside the protective box 208. The driven gear 207 is also rotatably connected to one of the synchronous pulleys 205 and is located on the synchronous pulley 205. The drive gear 206 also meshes with the driven gear 207 and is located outside the driven gear 207. The protective box 208 is disposed on the support box 203.

[0050] In this embodiment, the driven gear 207 is connected to one of the synchronous pulleys 205. When the driven gear 207 rotates, it transmits power to the synchronous pulley 205, thereby activating the transmission system of the synchronous belt 204 and the synchronous pulley 205 in the lifting mechanism 110, realizing the transmission and conversion of power.

[0051] Secondly, the number of external teeth of the driven gear 207 is greater than the number of external teeth of the driving gear 206.

[0052] In this embodiment, based on the principle of gear transmission, when the driving gear 206 rotates once, the driven gear 207 rotates fewer times than the driving gear 206, thus achieving a speed reduction effect. This reduces the rotational speed of the driven gear 207. Simultaneously, according to the law of conservation of power and the relationship between torque and rotational speed, with a constant power, a decrease in rotational speed will increase torque. The driven gear 207 transmits the increased torque to the synchronous pulley 205 connected to it, which in turn drives the lifting screw 202 to rotate through the synchronous belt 204 and the synchronous pulley 205 transmission system. This provides sufficient power for the lifting of the pallet rack 101, better overcoming the weight of the goods and potential frictional resistance, ensuring that the stacker crane can stably and reliably handle goods of different weights, and adapting to the diverse operational needs in logistics warehousing.

[0053] Based on the second embodiment, please refer to Figure 10 The present invention also provides a control method for an explosion-proof stacker crane used in logistics warehousing, applied to the aforementioned explosion-proof stacker crane used in logistics warehousing, comprising the following steps:

[0054] S1: By using the push handle 116 and the caster wheel 117, the explosion-proof stacker is moved to the designated location where goods need to be picked up, and the staff places the goods on the insert rack 101;

[0055] S2: Start the dual-axis motor 109. The dual-axis motor 109 drives the worm gear 108 to rotate clockwise. The worm wheel 106 rotates accordingly, which in turn drives the rotating shaft 104 to rotate. This causes the half-fan explosion-proof cover 105 fixed on it to rotate around the rotating shaft 104. The two half-fan explosion-proof covers 105 merge inward to cover the goods.

[0056] S3: Then, based on the push handle 116 and the universal wheel 117, move the explosion-proof stacker to the position where it needs to be stacked, control the dual-axis motor 109 to drive the worm gear 108 to rotate counterclockwise, and the two half-fan explosion-proof covers 105 unfold inward and outward respectively;

[0057] S4: Based on the stacking height requirements of the goods, the moving end of the lifting mechanism 110 is controlled to make the insert frame 101 lift the goods. When the goods reach the specified stacking height, the operation of the lifting mechanism 110 is stopped, and the goods are accurately placed at the target position.

[0058] S5: After the goods are stacked, control the lifting mechanism 110 to lower the insert rack 101 to the initial position.

[0059] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
